本文是对《工程测量》88年第5期“空间圆曲线测设问题的探讨”一文的补充,上述文章是将二空间相交直线之一放在新设的坐标轴上,而本文则将二空间相交直线的交点放在所设座标原点上,以空间解析几何为基础推算出具体所需空间圆曲线元素值,使空间曲线测设在应用上更具有广泛性。 This article is a supplement to the article “Exploration of Spatial Circle Curve Surveying Problem” in the “Year of Engineering Survey” No. 5, 88. The above article is to place one of the two space intersecting lines on the newly set coordinate axis. The intersection points of the two spatially intersecting straight lines are placed on the origin of the set coordinates, and the elemental values ​​of the space curves required for the specific space are calculated based on the spatial analytical geometry, so that the spatial curve measurement is more widely applied.
